Backcalculation Infrastructure Software

Our PSIBackCalc3D™ software is capable of back-calculating layer moduli from deflections obtained from Heavy Weight Deflectometer (HWD) tests.

Used together with our non-destructive data collection van and HWD data, we can provide back-calculation of moduli for a complete analysis of urban streets and rural pavements.
